I'm trying to run Christopher McBee's virustotal nugget from the SVN. I'm using a fresh install of Ubuntu 9.10 and got razorback running.
The problem is with the json library required for virustotal, libjson0-dev is in lucid but not karmic, I tried libjson-glib-dev, but couldn't get it to work.
So I found and built json-c from here: http://oss.metaparadigm.com/json-c/ .  I added my API key to the source and ran make, but when I run it, it seg faults.

After a lot of searching, this thread http://stackoverflow.com/questions/1691014/qt-application-crashing-immediately-without-debugging-info-how-do-i-track-down
leads me to believe there's a static initializers problem in the library. 
So I'm back to trying to find a json library, what one should I use in Ubuntu 9.10?  Or should I start over in 10.4/10.10?
